Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
Its capabilities exceed those of any model we’ve ever made generally available.
🚨 THIS HAS NEVER HAPPENED IN HISTORY.
We are in the middle of a war and the S&P 500 is about to hit a new all time high.
When the war started, the S&P 500 crashed 8.5%, wiping out $5.3 trillion from its market cap.
And now from the bottom on March 31, it is up almost 10%, adding $6.2 trillion back.
And the strangest thing is, the war is not over. Negotiations have failed.
The US blockade of Iranian ports is active. Oil is still at $93. Inflation just jumped to 3.3% in March, the highest in nearly two years, The Fed cannot cut rates.
Yet S&P 500 is just 1% away from a new All Time High.
We just released Gemma 4 — our most intelligent open models to date.
Built from the same world-class research as Gemini 3, Gemma 4 brings breakthrough intelligence directly to your own hardware for advanced reasoning and agentic workflows.
Released under a commercially permissive Apache 2.0 license so anyone can build powerful AI tools. 🧵↓
